I have recently installed a piece of 32-bit software which uses Awesomium on my 64-bit Linux machine. Having troubles launching it, I eventually found out that Awesomium depends on Gnome's
libgconf, which I didn't have installed and whose installation pulled in a huge amount of dependencies.
From what I have gathered, using GConf directly is not recommended anymore and applications should be ported to
glib's GSettings. Apart from that, I'm not sure if and how Awesomium uses GConf, so I wonder: how did this dependency come to be?
